Description

The GreenVulcano® ESB http-call plug-in allows the data exchange through the HTTP protocol. This subsystem represents the implementation of the VCL deputy to perform GET and POST to HTTP / HTTPS servers.

VulCon / GV Console Configuration

Use the HTTP VCL plugin if you want to call HTTP methods on remote servers.

The http-call Element is used by: Channel and routed-call. Its attributes are:

Attribute Type Description
type fixed This attribute must assume the value call.
class fixed This attribute must assume the value it.greenvulcano.gvesb.virtual.http.HTTPCallOperation.
name required Operation name. Used in the Flow section to associate workflow nodes to VCL operations.

Might contain the following sub-elements:

endpoint

The endpoint Element is used by: http-call. Its attributes are:

Attribute Type Description
host required Host to connect to.
port optional Port where the service is exposed. Default port is '80'.
secure optional Defines if the endpoint connection is secure or not. If secure is 'true', the default connection protocol will be 'http'; otherwise, the default connection protocol will be 'https'. The default value is 'false'.
custom-protocol optional Can be one of those defined locally for this 'http-call', or globally in GreenVulcano® ESB on GVSupport configuration.
Attribute Type Description
conn-timeout optional Defines the connection timeout, in ms. Default to 10000ms.
